Creep tumors are created by queens or by other creep tumors and must be built on creep.

The creep tumor is burrowed, rendering it stealthy. The stealth enables "offensive" creeping. In the single-player Wings of Liberty campaign however, creep tumors are always able to be seen even without detector units. Later in Heart of the Swarm campaign it gained its burrowed ability again. Many missions feature the zerg dropping sacs on the player's base, spawning a creep tumor in addition to the occasional reinforcing zerg units.

The queen forces a creep tumor out of her bowels.[2]
Alternatively, each creep tumor may create a single additional creep tumor, using the same build time but no energy cost. This changes the tumor's appearance.

The following section contains information from a previous version of StarCraft II which is no longer valid.

In older versions of StarCraft II the creep tumor could evolve into a shrieker.[4] Shriekers extended the range of swarm clutches to anywhere within its own detection radius, and through careful positioning could effectively double their attack range in some cases.[5]

Creep tumors used to be produced from hatcheries within a given range of the producing building.[6]

Patch 1.5

On August 2012, Antiga Shipyard was be used to playtest upcoming changes. Blizzard reduced the creep tumor build radius, vision radius, and creep spread radius from 10 to 8, in order to make it more difficult for a zerg player to spread creep over the entire map.[7]
